noUBLE-sEAmING MACHINE.

To all whom it may concern: n Be it known that we, OLAF Os'rLIN, a citixen of the United States, and a resident of I double seaming machines. The object of the invention is to provide a donble.seamin machine of high capacity so that the hen s or covers u on filled or other cans may be very rapid y secured to the bodies by perfect and hermetically tight double seams.

The invention consists in connection with a series of can holding chucks or disks mounted upon the stationary frame of the also mounted upon the stationary frame of the machine, and each furnished with .a plurality of seaming rollers and means for actuating the same, a series of opening. and closing can centering jaws for centering the runs with the can holding disks and rotary seaming-heads before the can holding disks .or chucks close upon the cans, acan conveyor, and a can teeder operating to s1-.

multaneously feed a plurality of cans from the conveyor to the can holding chucks or disks, and can cjectors or discharging devices for delivering 01' discharging the sea-med cans from the can holding and seaming devices.

The invention further consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described.

In the accompanying drawing forming a part of this specification, Figure 1 is a front elevation of a double seaming machine cmbodying the invention. Fig. 2 is an end elovation. Fig. 3- is a vertical section on line 33 of Fig 1. Fig. 4 is a horizontal set tion on line 4-4 of Fig. 1. Figs. 5 and 6 are detail sections of one of the rotary seaming heads on lines 55 and 6-6 of Fig 3. The section line 5-5 is also shown in ig. 7. Fi 7-is an enlarged vertical sectionof broken line 7--7 of Fig. 5. 8 is a detail plan view of one of the seaming roller Specification of Letters Patent.

a series of rotary seaming heads the rotary seaming heads on the Patented May 4, 1909.

levers and Fig. 9 is a detail elevation of a portion of one of the rotary seaming heads.

In the drawing, A represents the frame of'the nnmhine, B B the upper and lower can holder chucks ordisks, preferably four in number, the several in a. row o in line with eachothenC C opening and closing rancentering jaws or clampspreferably four pairs, or one pair for each pair of can holder chucks or disks B B, D D the rotary seaming heads, one

airs being arranged for each pair of can holders, E the can feed table, F the can conveyor, Gr the can feeder and G the. ejectors or discharge devices for the seamed cans.

The frame A may be of any suitable construction adapted to give support to the other parts.

Each of the upper can holder chucks or disks B is removably secured by screw threads 6 to an upright stationary shaft or ste n-b which is ad ustably secured. to the frame of the machine by threadedends so that it may be adjust d up or down as re aired for cotiperation with the seaming rolers. I Each of the lower can. holder chucks or disks B is furnished with astem b and is reciprocatcd-u and down as required in the guide I) on e frame of the macliine by means of an 0 crating lever 77*, pivoted to the frame at and which lever is connected at its other end by a clamp sleeve 11'' with the operating s'ten'i h of said holder B tuated by a cam through a connectin link It having a ml er in 'engag'in the can;

Each of the o crating levers b is ac- ]nanda' guide fork it fitting astri e the cam shaft H.

The series 0t pairs of can centering ews or clamps C C are reciprocatbd or opened and closed as requlred by recipmcating slides O C on the frame of the machine, the slide C having arms C to which the jaws C are secured, and the slide C having arms C to which the opposing clamps or ja ws C are secured. The'slides or reciprocating bars C C are actuated as required b means of a lever C to which said slides C 'are pivotally connected. and which lever C is actuated byla 'cam CT on the" u right shaft C whichlisoperated from t e it iaft K through a worm and worm on .t' e cam shaft.- 'H' link I the connecting :link d", lever (1 and Each of the rotary seaming heads D is secured to a rotating sleeve D surrounding the stationary stem b of the upper can holder chuck or disk, and is continuousl rotated as required from the driving shaft K through the spiral gears D D.

Each of the rotary seaming heads D is furnished with a plurality of double seam ing rollers d, preferably four in number, one pair of rollers d d being seam forming rollers, and the other pair d d seam closing rollers. I

Each of the seaming rollers d .01 d are preferably journa-led u on a seaming roller e'er (2, having an a 'ustable member or arm d, a fulcrum mom or d and an operating arm (1 furnished with a cam or incline d adapted to be engaged by a cam or incline d on a reciprocating sleeve d which rotates with "the seamin head, but is adapted to be moved up and t iown there on as required to properly actuate the seaming rollers. Theseaming roller actuating sleeve (i of each rotary seaming head is reciprocated as required to actuate the seaming rollers by meansof a cam h on the cam shaft H throu' hthe connecting ilcrum sleeve rl which is secured or confined on said operating sleeve d b collars d". The adjustable arms J of tie seaming roller levers a? are preferably furnished with adjustable notches or devices d" d to facilitate the adjusting or setting of the same for operation upon cans of different diameters and also with interfitting slots and pins d d.

The cams or inclines d through'which the seaming rollers cl perform the first or seam formin operation, are preferably movably secure totthe o crating sleeve (i by a pivot pin (1" and'hel yieldingly in position b a spring tl so as to cause the seaming r0 ler to exert a yielding pressure.

The can feed table E is preferablyfurnished with guide rails E for the cansfand with a way or channel E for the can conveyer F.

The can conveyor F is preferably an endless chain furnished with arms f to engage the cans and feed them along. The conveypr F is actuated by a sprocket wheel F on the shaft F having a bevel gear F which meshes with a bevel gear F on the upright shaft G".

The can feeder G preferably consists of a transversely reciprocating bar adapted to engage simultaneously as many cans on the feed table E as there are rotary seaming heads D. As the can conveyer F moves the cans along the feed table E, the transversely reciprocating 'feeder G feeds or pushes four cans simultaneously off of the conveyer F onto the lower up and down reciprocating can holders B, the cans being approximately guided into position by transversely extending uides E on the feed table. Then the severaipairs of can centering jaws C C close upon the can bodies and center them accurately with the can holders D D and the rotary seaming heads D. Simultaneously with the closing of the can centering jaws C C the lower can holder B moves upward and firmly clamps the can between itself and the upper can holder chuck or disk 13, and then the operating sleeves d of the rotary seaming heads actuate the seaming rollers, first the seam forming pair of rollers d d, andsubsequently the seam closing rollers 03 d. The seaming rollers-are then withdrawn from contact with the finished scam, the centering jaws C C open and the lower can holder chucks or disks B descend to the level of the can feed table E and then the ejectors or can discharging devices G ash or deliver the seamed cans out of t a machine onto the can discharge conveyor M, which is refer-ably a belt actuated by a pulley M.

Jach of the ejectors or can discharge devices G preferably consists of a bent arm secured to the can feeder G,-and furnished with a dog 9 for engaging the can at its lower end The lower chucks B are furnished with can ejectors The can feeder G is preferably transversely reciprocated as required by means of cam h on t 1 necting links 5 levers g and connecting links 9.

The lever b? for operatin the lower can holder chuck B is provide with a slot 6 for connection with the link h so that the throw of the lever 7) and chuck B may be adjusted as required for operation upon cans of different heights.
